In October 2025, F5 rotated its signing certificates and keys used to cryptographically sign F5-produced digital objects.

As a result:

    BIG-IP and BIG-IQ TMOS product versions released in October 2025 and later are signed with new certificates and keys
    BIG-IP and BIG-IQ TMOS product versions released in October 2025 and later contain new public keys used to verify certain F5-produced objects released in October 2025 and later
    BIG-IP and BIG-IQ TMOS product versions released in October 2025 and later may not be able to verify certain F5-produced objects released prior to October 2025
    BIG-IP and BIG-IQ TMOS product versions released prior to October 2025 may not be able to verify certain F5-produced objects released in October 2025 and later

I wonder if there's a bet to be made on future 8K disclosures following quietly updated signing keys. A bet against F5 placed this morning would've only made 3.6%.
